How do I iterate over arrays in JavaScript?

You can use several methods like for loops, forEach, map, and more. Which one would you like to know about?

Can you explain the forEach method?

Sure! The forEach method executes a provided function once for each array element. Here's a simple example:

const fruits = ['apple', 'banana', 'cherry'];
fruits.forEach(fruit => {
  console.log(fruit);
});

What about using a for loop?

A for loop is a traditional way to iterate over arrays. Here's how you can do it:

const fruits = ['apple', 'banana', 'cherry'];
for (let i = 0; i < fruits.length; i++) {
  console.log(fruits[i]);
}

Are there any other methods I should know about?

Yes! You can also use the map method to create a new array based on the original one. It's quite powerful!
